obovate, about equally narrowed to the slenderly acuminate apex 

 and to the acute base, 8 to 10 cm long, 3.5 to 5 cm wide, the 

 margins prominently and acutely apiculate-sen-ate except in the 

 lower 1 cm and the margins of the acumen which are entire; 

 nerves 7 or 8 on each side of the midrib, distinct, anastomosing, 

 the reticulations lax; petioles furfuraceous-pubescent, about 2 

 mm long. Inflorescence terminal, slightly pubescent, solitary, 

 including the peduncle up to 13 cm in length, each bearing one 

 or two, rather many flowered, 2 to 3 cm long spikes. Flowers 

 white, the bract orbicular-ovate, irregularly toothed, 1.7 to 2 

 mm long, rounded. Pistillate flower: Ovary narrowly ovoid, 

 somewhat narrowed at both ends, about 2 mm long, glabrous. 

 Staminate flowers: Antheriferous scale 3-partite, the lobes ob- 

 long, rounded, the central one about 4 mm long, 1.2 mm wide, 

 bearing an oblong, 1.2 mm long, 2-celled anther, the lateral lobes 

 about as wide, one-half as long, each bearing a 1-celled anther.

Probably as closely allied to Chloranthus henryi Hemsl. as to any other 

 species. It is distinguished, however, by its pubescent branchlets and 

 lower surfaces of its smaller leaves, its inflorescence reduced to 1 or 2 

 spikes, and its smaller flowers. From its closest Philippine ally, C. philip- 

 pinensis Merr., it differs in its much smaller, pubescent, shortly petioled 

 leaves, and its larger flowers.

A slender vine, nearly glabrous, the branches brownish when 

 dry, glabrous, deeply sulcate. Leaves ovate, membranaceous, 

 glabrous, of about the same color on both surfaces, somewhat 

 shining, 14 to 17 cm long, 8 to 10 cm wide, entire, the apex 

 acuminate, the base deeply and prominently cordate, the sinus 

 about 2 cm deep, 1.5 to 2 cm wide, often obovate, the basal lobes 

 rounded; basal nerves 3, the lateral pair soon forked, and 

 its lower branches soon forked again, the lateral nei-ves above 

 the base about 3 on each side of the midrib, prominent, the re- 

 ticulations very lax ; petioles 4 to 7 cm long, glabrous. Racemes 

 axillary, solitary, the rachis slender, slightly pubescent, about 

 3 cm long, each raceme bearing about 6 flowers, not all de- 

 veloping at one time, each flower subtended by an ovate-lanceo- 

 late, acuminate, slightly pubescent bract, the pedicels minutely
